alt @from it may concern Be it known that I, Lewis S. VVATRES, a

citizen ot Ithe United States, residing 1n Scranton, in the county of Laekawanna,

State of Pennsylvania, have invented a certain new and useful Means for Determining 'the Weight or Fuel Carried by Aa Locomo tive-Tender, of which the following is a specilication.

The invention of this application is a di vision of an application filed by me May 16,

1913 under Serial No. 767,997, and consists of an organization by which variations. in the weight of the fuel carried by the tender of a locomotive may be readily determined by a suitable indicating device, actuated by a closed liquid system, under control of operating means forming a part of the king bolts of the car body and truck connections.

ln the accompanying drawings: Figure 1 is a side elevation partly in section showing the lower part of a tender and its means of support on thetruck holsters. plan View of one of thetrucks showing the specially constructed king bolt', and: Fig. 3 is detached' View rof the parts constituting the weighing apparatus.

The tender l with its body bolsters 24, 2l, the trucks 3l, 3l, and truck bolsters 26, Q6, are of; ordinary construction. Each king bolt is divided into two parts, having interposed between them a yielding liquid conihe central part of which is secured the 'upper part 280i the king bolt, a diaphragm 3l, to which isvsecured the lower part 29 of the lling bolt, a spacing ring 12, between the diaphragme at their peripheries, and'bolts and nuts '13, for holding the parts of the liquid containers together. T he upper part 23 or' the king bolt seats in a' socket on a truck bolster and the lower Apart Q9 seats in a socket 25a on the bolster of a truck. A pipe line 33 longitudinally arranged connects the liquid containers together bympples 36, which extend from the spacing rings 13, and thisV pipe line by a transverse section 37 connects with the weight indicatingy de?" vice, which is carried at a suitable place on the tender. This 'weight indicating device consists of a two part casing 20 with a dla'- Fig. 2 is a.

ph'ragm 38 interposed between them, the

composed ofthe lliquid containers of the 55 'king bolts the chamber of the casing 20k beneath the diaphragm 38 ahd the connecting pipes. The liquid. in this closed system should be such as to be unaected by ordinary low temperature and preferably non 60 conipressible, as, for instance, it may be mercury, alcohol, kerosene, etc.

All'of the diaphragms will be made of a suitable yielding material, as steel,'of a,

strength adequate to the work they are si1b 65 mitted to. They are preferably corrugated, as shown, to increase their capacity for compression and reaction.

The diaphragm 38 of the gage may be phragm' 38, its height in the tube beingy determined by the pressure caused to bear on tainer 35, consisting of a diaphragm 30, to the diaphragm 38, corresponding to the capacities ot the liquid containers 35, as

tender.

`\'l`he sca-le" plate 22 to which the gage tube 21% is held may be secured to any suitable part oflthc walls of the tender and may be protected from injury, etc. by a suitablecasl. A While l have shown both diaphragme; of the liquid containers infr corrugated, and deem that arrangement the most ellicicnt, it is not in fact necessary. -l rigid plate may be substituted for'one of them. The upper diaphragm 30 of the liquid container 35 may be secured to a platey which is secured to the bolster 2l of the truck, the other parts 'ot' the king bolt and liquid retainer being .provided with means to actuate any style of changedby'" variations of load carried, by the.

less space between the bolster and truck thanthat vshown in the drawings.

I claim:

l. A locorngitive tender having combined with it andinteiposed between it and its carrying trucks a closed liquid system comprising' a liquid `container 'and having one or more diaphragms acting as a support for the tender body, and king bolts secured to the liquid containers whereby variations of load may be indicated by a gage controlled by the liquid in the closed system.

2. The combination with a locomotive tender and its carrying trucks of king bolts having mediate their ends yielding liquid containers, a gage easing and pipes eennecting the containers and gage casing constitubing a closed liquid system, whereby variations of pressure upon the liquid in the containers due to Variations of load of fuel carried by the tender may be indicated by inaeee corresponding changes of pressere in. gage casing,

3. The combination with a locomotive tender and its carrying trucks of king' having mediate their ends yielding iiquid containers, a gage casing divided by a diaphragni, pipes connecting the contain rs and. one side of tbe gage easing eonstituting; a closed liquid Ysystem, and a gage tube eze# tendingv fron-i the other side of the gage easing.i whereby variations of pressure upon the liquid in the containers due to Variations of lead of fuel carried by the tender may be indicated. by corresponding of pressure in the gage casing'.
